Serum Profile of Thyroid Hormones from Birth to Puberty in Buffalo Calves and Heifers

Abstract

Growth is outcome of interactions among several factors, where thyroid hormones play a key role in coordination of these factors and the information of thyroid hormones in relation to growth in buffalo calves and heifers is not adequate. Thus the study was conducted on Murrah female buffalo calves and heifers, varying in age from newborn to 30 months. The study investigated the serum thyroid patterns in female Murrah buffalo calves and heifers from birth to puberty. The thyroid stimulating hormone concentration did not differ and remained almost the same from birth to 4-6 months. The thyroid stimulating hormone then gradually increased and reached a highest value at 24-30 months. The concentration recorded at 21-24 months and 24-30 month i.e. at the age of attaining the puberty, was about 3-4 times higher than recorded at birth. The T3 concentration recorded at 0-7 days of age was significantly higher than recorded for other age groups, except at 18-21 months, 21-24 months and 24-30 months. The T3 concentration did not exhibit specific trend during the ages 16 days-1 month to 15-18 months. The highest T4 concentration was recorded in 0-7 days old buffalo calves. The concentration decreased to lower value at 1-2 months. The T4 concentration from 2-4 months of age increased significantly and the values remained almost similar with minor fluctuations upto 24-30 months. The T4: T3 ratio recorded at different ages did not exhibit specific trend.

Can Emblica officinalis and Tinospora cordifolia supplementation possess immunomodulatory and adaptogenic properties in murrah buffalo calves?

“…The possible reason for such results might be due to antioxidant, vitamin C which is present in both herbal plants. Our findings are in agreement with the reports of Jain (2006) and Ingole et al (2012), who reported that, there was higher T 3 and T 4 concentration in 0-7 days old buffalo calves and there after the concentration decreased to lower values at 1-2 months as observed in our experimental findings.…”

Effect of age and season on the thyroid hormone activity of Mizoram strain female mithun (Bos frontalis)

“…The TH play a key role in co-ordination of different factors involved in growth, which is of great economic importance as far as the livestock enterprises are concerned [ 5 ]. TH directly influence growth by altering biochemical reactions; and being anabolic hormones, cause positive nitrogen balance and promote growth and development [ 5 ]. In the present study, the TSH levels were lowest in calves and increases among the heifer and the level decreases in the adult.…”

“…In animals, TH is required for normal growth and development indicating a pivotal role in growth regulation. Since they are necessary for normal growth; optimal concentrations of TH act as growth stimulators [ 5 ].…”

Role of Infrared lamps in cold stress alleviation during winter in Murrah calves

“…high levels of triiodothyronine and thyroxine at birth might be due to an early adaptation of the calf to the external environment. Ingole et al (2012) also reported significantly (P<0.01) higher values of thyroid hormones in zero to seven days old buffalo calves. The higher values of T 3 and T 4 in calves of G 1 might be due to effort of calves to adapt their metabolic balance to cold conditions.…”
